摘要： A membrane digital analog switch includes an input button surface adapted to receive an input pressure from a user, and a digital switch positioned below the input button surface to generate a digital switch activation signal when the received pressure on the input button surface is greater than or equal to a specified digital pressure threshold. The membrane digital analog switch also includes an analog switch adapted to generate an analog switch activation signal when the received pressure on the input button surface is greater than or equal to a specified analog pressure threshold. The specified analog pressure threshold is greater than the specified digital pressure threshold, the digital switch activation signal is a binary digital signal, and the analog switch activation signal is variable and corresponds to an analog sensed value of the received pressure on the input button surface.
